title: [Frequency of abortion and seroprevalence of the principal diseases causing ovine infectious abortion in the area of Rabat (Morocco)].
abstract: A survey was carried out on 23 sheep flocks to estimate the frequency of abortion as well as the prevalence of antibodies against abortive infections. During the visit of each farm, a questionnaire was completed with the collaboration of the owner and blood samples were collected from all aborted ewes and some of those with normal lambing. A rate of 7% abortion was reached in both aborted and normally lambed ewes. Anti-Chlamydia psittaci antibodies were the most frequently detected (14 flocks). Anti-Coxiella burnetii and anti-Toxoplasma gondii antibodies were found in 9 flocks, whereas anti-Brucella and anti-Salmonella abortus ovis were present in only 1 flock each. None of the 5 infections was detected in 2 flocks. Mixed infections were prevalent: 13 flocks were simultaneously infected by at least 2 abortive pathogens. The procedure used does not allow the cause of abortion to be identified in all cases.
